[kubernetes] 공기 흐름 스케줄러가 kubernetes executor로 시작하지 못함

https://github.com/helm/charts/tree/master/stable/airflow helm 차트 를 사용 puckle/docker-airflow하고 kubernetes가 설치된 v1.10.8 이미지를 만들고 helm 차트에서 해당 이미지를 사용하고 있습니다.

내 스케줄러에서 다양한 소스가 조언하는 것처럼 설정을 시도했습니다.

AIRFLOW__KUBERNETES__KUBE_CLIENT_REQUEST_ARGS: {"_request_timeout" : [60,60] }

조타 가치에서. 그 누구도 내가 뭘 놓친 아이디어가 있습니까?

여기 내 가치가 있습니다.

airflow:
  image:
     repository: airflow-docker-local
     tag: 1.10.8
  executor: Kubernetes
  service:
    type: LoadBalancer
  config:
    AIRFLOW__KUBERNETES__WORKER_CONTAINER_REPOSITORY: airflow-docker-local
    AIRFLOW__KUBERNETES__WORKER_CONTAINER_TAG: 1.10.8
    AIRFLOW__KUBERNETES__WORKER_CONTAINER_IMAGE_PULL_POLICY: Never

    AIRFLOW__KUBERNETES__WORKER_SERVICE_ACCOUNT_NAME: airflow

    AIRFLOW__CORE__SQL_ALCHEMY_CONN: postgresql+psycopg2://postgres:airflow@airflow-postgresql:5432/airflow

persistence:
  enabled: true
  existingClaim: ''

workers:
  enabled: false

postgresql:
  enabled: true

redis:
  enabled: false

편집하다 :

helm 값에서 환경 변수를 설정하려는 다양한 시도 .yaml이 작동하지 않아 추가했습니다 (큰 따옴표와 작은 따옴표에주의하십시오)

ENV AIRFLOW__KUBERNETES__KUBE_CLIENT_REQUEST_ARGS='{"_request_timeout" : [60,60] }'

후 나의 airflow-scheduler포드 시작하지만 내 스케줄러 포드 오류를 다음과 점점 계속.
